Check whether cell at indexPath is visible on screen UICollectionView

Question

I have a CollectionView which displays images to the user. I download these in the background, and when the download is complete I call the following func to update

Answer 1

Get current available cells

// get visible cells 
let visibleIndexPaths = followedCollectionView.indexPathsForVisibleItems

Then check if your indexPath is contained in the visibleIndexPaths array or not, before doing anything with cells.
